Well, maybe regression is not a right word in this case but the difference is very noticeable.

I'm running the latest version at the moment using OpenGL 4.1 Core Profile on macOS. Value of gl_lightmode CVAR is 3 (default). Command line:

Code: Select all

-iwad heretic +map e1m2 "+warp 1711 -322" +gamma 2 +notarget

Hm. Seems I was wrong about the light level cutoff. I had to rewrite the light level calculation for levels below 100 to avoid this steep dropoff.
